The cart's acceleration will triple as the numerator in the expression for the acceleration will triple when m 1 is tripled. The cart's acceleration will remain the same as the total mass is constant during the experiment. The acceleration will increase by a certain value but not by a factor of 3.

11/25/11 8:54 PM Lab 3 - Newton's Second Law: PostLab (e) Write Newton's Second Law equation (in the form F net = ma ) for m 1 in the y -direction. It is important to use the correct signs for each of the forces. Motion in the upward direction is positive and motion in the downward direction is negative. (Be sure to enter your answer in the above form with the sum of the forces in the left hand side answer box. The right hand side answer box should have the appropriate form of ma . Use the following as necessary: a , f , F N , m 1 , and T .) g , (f) Write Newton's Second Law equation (in the form F net = ma ) for m 2 in the y -direction. It is important to use the correct signs for each of the forces. Motion in the upward direction is positive and motion in the downward direction is negative. (Be sure to enter your answer in the above form with the sum of the forces in the left hand side answer box. The right hand side answer box should have the appropriate form of ma .
